Google has now started rolling out the latest Android version of mobile OS “4.0.4 Ice Cream Sandwich” for Nexus S so you can manually update your 4G Nexus S phone system. Few days ago, the search engine giant announced that the Android 4.0.4 ICS update for the GSM and HSPA+ versions of Google’s Nexus S handsets. Today, by publishing a post on its Google+ page stated that they have released the Android 4.0.4 Build IMM76D Ice Cream Sandwich to the public.

Those who are eager to get the ICS update right now, can follow our guide ready which is waiting for you to implement it on your Android GSM device. The 18MB update file can only be installed over the stock IML74K 4.0.3 firmware, but it’s a fairly simple process and with a little guts and nerves at hand, you can go about it without the risk of messing up your Nexus S at all.

DISCLAIMER : Obviously, Grabi will not be responsible if you lose any data or your device gets damaged in the following of this guide. Proceed at your own risk.

However, the update was pushed through Nexus S users over-the-Air (OTA) in the very near future, which means, not connecting your device to the PC, you can upgrade.Once it has arrived, you’ll see an update notification on your Nexus S pull-down notifications bar. If you wish to see whether the update has been pushed out manually, then simply press Menu button then head over to Settings > About phone > System update.
